The Underwriting Agreement, the Indenture and the Note Certificates (as defined below) are referred to herein collectively as the “Transaction Agreements.”

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”).

We do not express any opinion as to the laws of any jurisdiction other than (i) the General Corporation Law of the State of Delaware, (ii) the Delaware Limited Liability Company Act, (iii) the California Revised Uniform Limited Liability Company Act and (iv) the laws of the State of New York, and to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as “Opined on Law”). We do not express any opinion as to the effect of any non-Opined on Law on the opinions stated herein.

Based upon the foregoing and subject to the qualifications and assumptions set forth herein, we are of the opinion that:

1. When duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Note Certificates will constitute valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms under the laws of the State of New York.

2. When the Note Certificates are issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Guarantees will constitute valid and binding obligations of each Guarantor, enforceable against such Guarantor in accordance with their terms under the laws of the State of New York.

The opinions stated herein are subject to the following qualifications:

(a) the opinions stated herein are limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

(b) except to the extent expressly stated in the opinions contained herein, the opinions stated herein are limited to the agreements specifically identified herein without regard to any agreement or other document referenced in such agreement (including agreements or other documents incorporated by reference or attached or annexed thereto);

(c) except to the extent expressly stated in the opinions contained herein, we have assumed that each of the Transaction Agreements (other than the Underwriting Agreement) constitutes the valid and binding obligation of each party to such Transaction Agreement, enforceable against such party in accordance with its terms;

(d) we have assumed that the limited liability company agreement reviewed by us of each Subsidiary Guarantor that is a limited liability company is the only agreement of the members of such Subsidiary Guarantor as to the affairs of such Subsidiary Guarantor and the conduct of its business, and we do not express any opinion with respect to the effect of any other agreement of the members of such Subsidiary Guarantor as to the affairs of such Subsidiary Guarantor and the conduct of its business;

(e) we do not express any opinion with respect to the enforceability of the Supplemental Indenture to the extent that it provides that the obligations of the Guarantors are absolute and unconditional irrespective of the enforceability or genuineness of the Indenture or the effect thereof on the opinions stated herein; and

(f) we do not express any opinion with respect to the enforceability of the provisions contained in Section 6.02 of the Supplemental Indenture to the extent that such provision limits the obligations of the Guarantors under the Indenture or any right of contribution of any party with respect to the Guarantees.

In addition, in rendering the foregoing opinions, we have assumed that neither the execution and delivery by the Company or the Guarantors of the Transaction Agreements nor the performance by the Company or the Guarantors of their respective obligations under each of the Transaction Agreements: (i) constitutes or will constitute a violation of, or a default under, any lease, indenture, instrument or other agreement to which the Company, the Guarantors or their respective properties are subject, (ii) contravenes or will contravene any order or decree of any governmental authority to which the Company, the Guarantors or their respective properties are subject, (iii) violates or will violate any law, rule or regulation to which the Company, the Guarantors or their respective properties are subject or (iv) requires the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of any jurisdiction.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Company’s Current Report on Form 8-K, being filed on the date hereof, and incorporated by reference into the Registration Statement. We also hereby consent to the reference to our firm under the caption “Legal Matters” in the prospectus forming a part of the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
